Diagnostic transverse ultrasound image of the left breast in a 64-year-old woman shows irregular hypoechoic nonparallel mass with indistinct margins corresponding to palpable finding, assessed as BI-RADS category 4. Both readers assessed mass as having associated echogenic rind with complete circumferential extent (arrowheads). Ultrasound-guided biopsy of mass yielded diagnosis of invasive ductal carcinoma (intermediate grade, luminal A molecular subtype, no lymphovascular invasion).

Question 4 from the Japan Diagnostic Radiology Board Examination 2024, representing a clinical scenario of a man in his 30s presented with transient dysphasia. The question asks to identify the most probable diagnosis from the following options: (a) glioblastoma, (b) hemangioblastoma, (c) metastatic brain tumor, (d) oligodendroglioma, and (e) primary central nervous system lymphoma (PCNSL). The correct answer is (d) oligodendroglioma. The figure also includes a summary of responses from four large language models, along with their legitimacy scores rated by diagnostic radiologists.
